Dr. J. Michael Waller argues in his new book, Big Intel, that two of the main agencies designed to protect us have become corrupted by ideology. He argues that implementing concepts including diversity, equity, and inclusion (DEI) priorities and others popular on the Left compromise the mission and tactics of the CIA and FBI.
J. Michael Waller is Senior Analyst for Strategy at the Center for Security Policy.
